Hello there. This is my first post on the boards and I was trying to get better @ GG and Baiken in particular. My question though is how do you do the air dash after j.d? Is a timing thing or are my inputs wrong? (Just double tapping 6 after). For reference i'm on advanced trial 7. I know the dust loops are important to her combos and just want to be consistent with them. I've done it a couple of times, usually late, but I wanted input from more experienced players. Thanks in advance.
